Will never fully embraced the pacifier for it's intended purpose, but he does think it is a funny toy. He usually smiles when he sees it and laughs when he plays with it. If he crawls around with it in his mouth the "right" way, he holds his breath and he quickly has to stop, sit and catch his breath. It is really funny to watch. Sometimes he will just sit and play with it and hang it out the side of his mouth like a cigar. We were going to throw away our collection of pacifiers when we realized Will didn't care for them around week 4 or so, but now we are glad we saved them!
